Summary

For reasons of animal health, milk yield and for environmental issues an optimal supply of protein and energy for dairy cows is essential. The aim of this study is to
examine potential protein and energy malnutrition and surplus in dairy herds. We present a comparison of the protein and energy supply between 18 conventional and
16 organic dairy herds. Initial results indicate an undersupply on energy in the first one hundred days of lactation in both the organic and conventional feeding regimes. It is easier to provide an adequate protein supply in conventional conditions in the first one hundred days than in organic ones. A balanced supply is guaranteed for a mere 21,3 % of the organic cows. In the second one hundred days this increases to 26,5 %, compared to 51,7 % in conventional ones. In high yielding organic dairy herds there is a shortage in energy and protein in the second one hundred days as well. In low yielding organic herds a surplus on protein over the whole lactation with possible
negative effects on animal health and ammonia emissions is observed. Once more these first results demonstrate the difficulty of providing a balanced nutrition in organic
dairy herds.
